Set key
Each ti me the set key is pressed, the limit is increased by 10 µS/cm or 6 TDS.
Hold the key for 3 seconds to reset the limit to zero. Programming the limit
ensures that a warning is issued when the ion exchange resin is spent. If
the set limit is exceeded, the backlight fl ashes red and an acousti c alarm
sounds. In additi on, the fl oati ng contact is switched over (only when using the
opti onal power supply unit).
Unit key
Use this key at any ti me to switch between electrical conducti vity (µS/cm)
and TDS (total dissolved solids) as well as between °C and °F. The fi rst two
are units of measurement for the amount of minerals dissolved in the water.
Most European component manufacturers use the unit of measurement
µS/cm (microsiemens per centi metre). Water hardness at the output of
the refi ll device can be determined using the following rule of thumb: 1 °fH
corresponds to approx. 20 µS/cm or 1 °dH corresponds to approx. 35 µS/cm.
